anyone have their episodes start this way?

hi. I have been doing halfway decent with my panic episodes. nothing really major that I havent been able to talk myself out of and it is usually over having to be in public or social situation.
Anyway, last night for no rhyme or reason, I was sitting on the ouch talking to my children when out of nowhere my heart started racing and my hands were shaking really bad. then thats when I start to panic a little. not really full on..only symptoms were heart racing, the shaking hands,a and me just thinking that this wasnt right and was scary.
I just want to know if this is normal for anyone else out there? thanks!

Thanks Sam. I guess I just hate how you dont have to be nervous or worried about anything and the stuff just hits you out of nowhere. I had aN EKG and cardiac bloodwork done three months ago and they said everything was fine. I just wish it werent so scary. I have become kind of agoraphobic lately, where I didnt want to leave the house. It seemed like i was fine here at home but to go anywhere would set the wheels in motion, so to speak.
I was so proud of myself and happy this week that I was able to go to the grocery store and feel completely normal and then yesterday afternoon even took my daughter to a bday party at a roller rink, mind you i did no skating. Although I am scared once again to venture out in public, Im not going to let it stop me... I cant.
I guess I was just looking for reassurance that this had happened in this manner for someone else( the heart taking off racing and then the other symptoms follow) Thanks again for your response:)

I'm going through these symptoms several times a day. They are extremely frustrating and you are not alone. It will get better.
